Review: Some problems but brilliant bit of kit - Had a problem where the bars of 5 star restraining knobs did not fit into track. However, by using my feather board bolts from same track it worked perfectly (thank you other desertcart user that suggested it). Once everything in place. Off you go. Brilliant piece of kit. Very happy and easy to use.
Review: Pricey - but I needed a treat - It's everything I expected it to be. Not sure how long the t-slot track will remain sturdy being mounted into MDF. For the price I would have expected it to have an aluminium base - but hey - I knew what I was buying. I see a question regarding will it fit on Lumberjack RS1500 - yes it will - though you need to borrow some parts off the front feather board that slot into the narrower t-track and all is then good and solid. Bit of a learning curve - of which i'm only part way through but initial cuts look promising. Deffo get an upcut spiral end bit for this - straight cut just tears everything out. So as it was a treat - I'm reasonably happy - but I could have made it myself for far less

## Questions & Answers

**Q: Has anyone an idea if this fits a charwood wo12 table top router table.**
A: sorry it will not fit mine unlessi cut it up which i have so i cannot send it back

**Q: Can you use the 1/2 AND the 1/4 finger together to get a 3/4 slot?**
A: Nope.

**Q: Does this fit a silverline bench top router table**
A: It comes with guides for 19mm slots ... which were no good to me. I attached it to a larger base with guide rails which fitted my router table, which worked OK.  I  did the same with the Rockler spline jig.

**Q: Is there any disadvantages to this being an imperial model?
I suppose I couldn't use metric bits could I?**
A: You could use metric bits but I'm guessing the holes cut out by the metric bits will be a fraction out from the brass inserts. Only way around this would be to accurately measure the brass inserts and compare them to the imperial. If needs be, either buy new bits to fit OR shave down/add shims (good use for an old feeler gauge) the brass inserts so they match the metric bits you have

Great results with this jig, straight out of the box. Works really well, good easy to understand instructions. Just make sure you do not use cheap router bits.
